Hello. I am interested in ray-tracing, and GPGPU. I work on the OpenCL acceleration of the BRL-CAD librt rendering pipeline:

• GSoC 2015 Abstract
• GSoC 2015 Project Proposal
• GSoC 2015 Development Logs

OCL librt Development Status

• Refactored dispatcher, shoot, optical renderer to process many rays in parallel when rendering an image or block.
• HLBVH object partitioning builder in C. traversal in OCL.
• GPU side database storage of OCL implemented primitives.
• Ported compute intensive or critical parts of the dispatcher, boolean evaluation, optical renderer to OCL.
• OCL dispatcher that performs the shot routines for a whole frame.
• OCL rasterizer that does the pixel pushing for a whole frame.
• OCL lighting modes: Phong, Diffuse, Surface Normals.
• OCL lighting modes: Multi-hit transparent (Single Stage Render Pipeline only).
• ARB8, EHY, ELL, EPA, ETO, PART, REC, RHC, RPC, SPH, TGC, TOR shot routines in OCL.
• Surface normal routines for all OCL implemented primitives.
• CPU HLBVH BOT shot construction with OCL traversal and interpolated per pixel normals.
